Given the points (-1,1) and (-2,1) on the line find the equation of the line
Triangle A'B'C' with coordinates of A' (-6,2)
Answer: (A), (B) and (E).
Step-by-step explanation: Given that ΔA’B’C’ with coordinates of A(-6,2),B’(-4,2), and C’(-6,-2) is the image of ΔABC after a translation of (x-3,y+2). We are to find the possible coordinates for the original vertices of ΔABC.
For vertex A, we have
So, the coordinates of vertex A are (-3, 0).
For vertex B, we have
So, the coordinates of vertex B are (-1, 0).
For vertex C, we have
So, the coordinates of vertex C are (-3, -4).
The mean diastolic blood pressure for a random sample of people was millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be millimeters of mercury, find a confidence interval for the true mean diastolic blood pressure of all people. Then give its lower limit and upper limit.
Answer:
(85.62, 90.38).
Step-by-step explanation:
The missing data can be assumed to be we have the following information:
¯x =88, s=10, n=70
Substituting the values in the following formula, we compute the 95% C.I for true population mean diastolic pressure as shown below:
95% C.I.=¯x±t(0.95,n−1)⋅Sm=¯x±t(0.95,70−1)⋅s√n=88±1.99⋅10√70=(85.62,90.38)
The answer is (85.62, 90.38).

1/2p-10=15
1/2p=25, subtraction property of equality
p=50, multiplication property of equality
therefore, P is equal to 50
if a,b,c,d are in continuous proportion then prove that (c+a) (c+d) = (b+c) (b+d)
Answer:
We must prove that (c+a)(c+d) = (b+c)(b+d)
Let us use principles from mathematical induction [tex] \frac{a}{b} = \frac{b}{c} = \frac{c}{d} = x[/tex]a=bx , b=cx, c=dxa+c = b + c c +d = b + d Such that (a+c)(c+d)=(b+c)(b+d)Rate positively and give brainlist

Adam and Simon start on bicycle trips from the same point at the same time. Adam travels east at 8mph and Simon travels south at 6mph. After how many hours are they 60 miles apart?
If Adam and Simon start on bicycle trips from the same point at the same time and Adam travels east at 8mph and Simon travels south at 6mph then after 4.28 hours the distance between them is 60 miles.
What is speed?Speed is the distance an object covers in a particular time period. It can be calculated as under:
Speed=Distance/ Time.
How to calculate time?We have been given the speed of Adam and Simon as 8 mph and 6 mph and we are required to find the time taken by both to be 60 miles apart.
Time=Distance/speed
We cannot find individually but we can find the average time.
Time=60/(6+8)
=60/14
=2.28 hours
Hence if If Adam and Simon start on bicycle trips from the same point at the same time and Adam travels east at 8mph and Simon travels south at 6mph then after 4.28 hours the distance between them is 60 miles.

ok so first you have to multiply 103.2 times 5 but that gives you 516 so the correct anwser is 103.4 x 5 = 517
if a rectangle have length of 10 inches and width of 8 inches what is the new area if each corner is cut by x^2
Answer:
[tex]80 - 4x^2[/tex]
Step-by-step explanation:
Area of a rectangle
A rectangle of width W and length L has an area of:
A = W.L
The given rectangle has a length of L=10 inches and a width of W=8 inches, thus its area is:
A = 8*10 = 80
[tex]A = 80\ in^2[/tex]
If each corner is cut by a square of x*x, then the total area will be:
[tex]A' = 80 - 4x^2[/tex]
The new area is [tex]\mathbf{80 - 4x^2}[/tex] square inches

Answer:
-450
Step-by-step explanation:
Please solve and explain the two problems.
Answer/Step-by-step explanation:
If two triangles are similar, their corresponding angles would be of equal measure of degree.
8. The 3rd angle of the smaller ∆ is x = 76°, while that of the larger ∆ is y = 44°. As we can see, the corresponding angles of both ∆s are not congruent or equal to each other. Therefore they ARE NOT SIMILAR.
9. x = 43°, while y = 106°.
Both triangles have corresponding angles that are congruent to each other.
Therefore, both triangles ARE SIMILAR.
the perimeter of a rectangle is 72 ft. the ratio of the length to width is 5:4. what are the dimensions of the rectangle?
Answer: 20 by 16
Step-by-step explanation:
5:4 OR 5x:4x
Perimeter = 2(l x w)
P = 2(5x x 4x)
P = 10x + 8x = 18 x
18x=72
x=4
5 x 4 = 20

If ABCD is a square and AC= 26, what is the length of BC
Answer:
BC = 18.385
Step-by-step explanation:
You can look at ABC as a right triangle and use the Pythagorean theorem to solve for BC. 26 squared is 676, 676 divided by 2 is 338, and finally the square root of 338 is 18.385. This is the length of BC and AB as well. Hope that helped
Answer: aprox 18.38
Step-by-step explanation:
you have a AC=, which is the hypothenuse of the right triangle, and isosceles
ABC
AB=BC, sides of a square
remember c^2=a^2+b^2 but and b are equal so we can say
c^2= 2a^2
c=a[tex]\sqrt{2}[/tex], 26/[tex]\sqrt{2}[/tex]=a
a=(26[tex]\sqrt{2}[/tex])2=18.38
Mario is playing an online puzzle game. He has 50 points and earns 3 points
for each puzzle he solves correctly. He will advance to the intermediate level
if his score is over 80 points.
Answer:
I think there might be more to this question, but the answer I have is
3x + 50 > 80
Step-by-step explanation:
If he has 50 points, needs higher than 80 points to advance to the intermediate level and receives 3 points for every puzzle he solves correctly, he must multiply the 3 by something to add to 50 to get a total amount higher than 80. Thus, 3x + 50 > 80 is the appropriate answer. Have a good day!

Missing length?? Please help me out
Answer:
The missing length is 12
Step-by-step explanation:

Determine the missing length (LS)
If RS = 28 and KS = 14
Then
[tex]KR = RS - KS[/tex]
[tex]KR = 28 - 14[/tex]
[tex]KR = 14[/tex]
The sides of the given shape are directly proportional.
This implies that:
[tex]KS : LS = RS : QS[/tex]
[tex]KS = 14[/tex]
[tex]RS = 28[/tex]
[tex]QS = 12 + LS[/tex]
[tex]LS = ??[/tex]
So, the expression becomes:
[tex]14 : LS = 28 : 12 + LS[/tex]
Represent as a fraction
[tex]\frac{14}{LS} = \frac{28}{12 + LS}[/tex]
Cross Multiply:
[tex]14(12 + LS) = 28 * LS[/tex]
Divide through by 12
[tex]12 + LS = 2 * LS[/tex]
[tex]12 + LS = 2 LS[/tex]
Collect Like Terms
[tex]2LS - LS = 12[/tex]
[tex]LS = 12[/tex]
The length of the missing side is 12
n automobile manufacturer claims that its van has a 37.4 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van since it is believed that the van has an incorrect manufacturer's MPG rating. After testing 280 vans, they found a mean MPG of 37.8. Assume the standard deviation is known to be 2.3. A level of significance of 0.05 will be used. Find the value of the test statistic. Round your answer to 2 decimal places.
Answer:
Then z(s) is out of the acceptance region, we reject H₀, doubts of the independent testing firm are valids
Step-by-step explanation:
We will develop a Hypothesis Test ( a 2 tail test since the independent testing firm is interested in finding out if there is an incorrect MPG rating from the manufacturer
Test Hypothesis :
Null hypothesis H₀ μ = μ₀
Alternative Hypothesis Hₐ μ ≠ μ₀
Significance Level α = 0,05 α/2 = 0,025
z(c) for α/2 from z-table z(c) = - 1, 96 and by symmetry z(c) = 1,96
Calculating z(s)
z(s) = ( μ - μ₀ ) / σ /√n
z(s) = ( 37,8 - 37,4 ) / 2,3 /√280
z(s) = 0,4 * 16,73 / 2,3
z(s) = 2,90
Comparison between z(c) and z(s)
z(s) > z(c) 2,90 > 1,96
Then z(s) is out of the acceptance region, we reject H₀, doubts of the independent testing firm are valids
